Rationale and Scope

Recently Distributed Ledger Technology (DLT) has become one of disruptive innovations with great potential to change our economy, culture and society fundamentally. DLT is an open, distributed, secure ledger that can record all transactions or online activities among relevant entities efficiently and in a verifiable manner.

DLT is in theory secure by design and an example of a distributed computing system with high fault tolerance. Decentralised consensus can therefore be achieved with a DLT.

It enables innovative financial/non-financial decentralized applications/service, such as e-services and IoT-based services, which eliminate the need for third party intermediaries. The outcome of this FG could be applicable to e-services.

This makes DLT suitable for the recording of events, payment transaction records, and other records management activities, identity management, transaction processing, and proving data provenance.

The FG DLT will be an open platform for relevant stakeholders – such as telecom regulators, financial regulators, services providers, platform providers, network operators; international organizations and industry forums and consortia – to share knowledge, best practices and lessons learned in the field with the objective of identifying the standardized frameworks needed to support the scaling up of applications and services based on DLT globally.

A FG DLT, as proposed under the auspices of TSAG, could address a number of topics of DLT, for example, use-cases and applications, requirements for the implementation, regulatory and policy aspects, security and privacy aspects, among many other aspects.
A FG DLT could consist of several Working groups that deal with those issues and topics mentioned above.

ITU-T Focus Group on Application of Distributed Ledger Technology (FG DLT)

The ITU-T FG DLT will analyse applications and services based on DLT that can be standardized by ITU-T study groups, identify best practices and guidance which could support the implementation of such applications and services on a global scale and identify a way forward that ITU-T SGs need to study in order to meet the urgent market needs.

It will develop a security standardization roadmap for interoperable services based on DLT taking into consideration the activities currently undertaken by the various relevant groups, standards developing organizations (SDOs) and forums and a regulatory toolkit which may be used by national policymakers and regulatory authorities from ITU Member States.

This Focus Group will work closely with relevant study groups in ITU-T and will also invite non ITU-T members to participate in its work.


To support the development of base materials for global standards for applications and services based on DLT, the objectives of this focus group include:


This Focus Group will work in close collaboration with all ITU-T study groups, especially SG11, SG13, SG16, SG17 and SG20. This FG DLT will coordinate with FG on DPM and with the United for Smart Sustainable Cities (U4SSC) initiative under auspicious of ITU-T Study Group 20 as appropriate.

This FG DLT will collaborate with relevant entities, in accordance with Recommendation ITU-T A.7.

These entities include the following: financial institutions, telecommunications regulators, financial regulators, non-governmental organizations (NGOs), policy makers, SDOs, industry forums and consortia (such as ISO TC 307, ISO/IEC JTC 1, GSMA, SWIFT etc.), payment systems networks, remittances companies, ICT companies, academic institutions, research institutions and other relevant organizations.

Specific Tasks and deliverables

Parent group

The parent group is TSAG.


See clause 2.3 of Recommendation ITU-T A.7.


See clause 3 of Recommendation ITU-T A.7. A list of participants will be maintained for reference purposes and reported to the parent group.

It is important to mention that the participation in this Focus Group has to be based on contributions and active participations.
